Rating: In chapter 2 of this book, I have found an example under header Use Business Interfaces, wherein the author has given a business interface `Order`, a remote interface `OrderRemote` and a class `OrderBean`. The mistake is in the signature of the class. `public class OrderBean extends Order, EntityBean ...` How can a class extend more than one interface? I suppose it is a printing mistake. The word `extends` should be replaced with `implements`. Hope in the next edition of the book, the mistake will be fixed by the author/publisher.
